I had the CIPA slip on mirrors on my 2005 F250. I used them once. The wind buffeted them so badly I could hardly see what was in any of the rear view mirror. I found a good pair of used towing mirrors that were direct bolt on/plug in and were heated and mirror electrically controlled. Best investment I ever did on that truck. My suggestion is not to mickey mouse around just get the upgraded mirrors and don't look back (no pun intended).
